title: Pathophysiology of muscle tone.
abstract: Pathophysiology of muscle tone is discussed on the basis of recent knowledge about motor system organization. Decerebrate rigidity, "pyramidal" spasticity and extrapyramidal rigidity served as models of muscle tone alterations in lateral and ventral motor system lesions.
